Abstract (en)

[origin: WO2015091381A1] The invention relates to novel polyorganosiloxane gels, produced by reacting (1a) unsaturated polyorganosiloxane resins and (1b) polyoxyalkylated, terminally unsaturated alcohols with mixtures of (2) Si-H functional polyorganosiloxanes of general formula HcR3-cSiO (R2SiO) a (RHSiO) bSiR3-cHc (I), where c represents 0 or 1, R can be identical or different and stands for a monovalent, optionally substituted hydrocarbon group comprising 1 to 18 carbon atoms per group, a and b are whole numbers, with the proviso that the sum of a+b is from 66 to 248, that the polyorganosiloxanes (2) contain Si-bonded hydrogen in amounts of between 0.011 and 0.044 wt. % and that the number of Si-H groups per molecule is on average greater than 2 and less than 5, and (2') Si-H functional polyorganosiloxanes of general formula HcR3-cSiO (R2SiO) a (RHSiO) bSiR3-cHc (I'), where R and c have the definitions given above, a and b are whole numbers, with the proviso that the sum of a+b is from 8 to 248, that the polyorganosiloxanes (2') contain Si-bonded hydrogen in amounts of between 0.045 and 0.35 wt. %, preferably between 0.045 and 0.156 wt. %, in the presence of (3) the attachment of Si-bonded hydrogen to catalysts that promote aliphatic multiple bonds, wherein (1a), (1b) and mixtures of (2) and (2') are dispersed in (4) diluents, preferable polyorganosiloxanes with 2 to 200 Si-atoms, or in organic diluents.
